This is useful and worked great, thanks!You just follow the manual install directions, right click a file and click on "find duplicates" from resulting right-click menu. Everything pops up w the filename in the search field, with search results already showing. Fast.

I must be missing something and it is probably due to the way I have installed everything in Windows 10.I am not sure if I need to create some additional directories or if i can simply modify the regedit to match what I have. Everything is installed under "c:\program files" with no additional subdirectories. I was just now wishing there was a way to use everything to locate and remove duplicates in a manner other than what I am currently doing which is tedious at best.Manually looking for groupings of the same name, checking to see if they are the same size and removing all but one of each group. I need to do this on multiple folders that each contain several hundred thousand files. Any advice on the correct statements to enable this feature in everything would be appreciated.

1.4 Beta has both dupe: & sizedupe: functions.(In the Index, you need to index the file size & also enable Fast size sort.)

You can combine them, something like:

> dupe: sizedupe: c: file:

Or even add a size to it:

> dupe: sizedupe: c: file: size:>2MB

Note that that finds file name AND (I believe its an AND) file size duplications - anywhere, not necessarily limited to C:, & also that name AND size are the only qualifications for "duplication", as in files meeting that criteria may not be (byte-by-byte) "duplicates".

AllDup has the concept of "Remove all groups where the files not exist at all source files".(That is a mouthful. Better way of saying it would be appreciated.)

DuplicateCleaner has the concept of "Scan Against Self" (Y/N).DuplicateCleaner, in an upcoming (time unknown) version will also have the concept of "protected" (or something like that I think it was).

If I'm understanding, I believe CloneSpy & Duplicate Cleaner may cover what you want.If I'm understanding AllDup, what it does is to scan everything (all selected directories), & then that particular option would remove files from ... oh, its confusing? But in any case, its method, in this case, would be less efficient then the others.
